PAD-DRYING MEANS FOR ranssine MACHINES.

Application filed June 10, 1926. Serial No. 115,065.

This invention relates to pressing machines and has for its object a particularly simple and'efiicient means for creating a draft of air either by suction or by blowing between the pressing elements and preferably through the pad, usually mounted on the buck of the machine, for the purpose of drying the pad,-and also the garment or other article .thereon.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention reference is had to the accompanying drawings in which like characters. represent corresponding parts in all the views.

Figure 1 is a fragmentary side elevation of a pressing machine embodying my invention. parts being'shown in section and the machine being shown as open.

Figure 2 is a similar view showing the ma chine v closed. L p

I have here shown my inventionas embodied in the standard type of pressing ma chine including a buck 1 mounted on the frame of the machine, a head 2 movable toward and from the buck and carried by a lever 3 pivoted at 4 to a standard 5 rising from the frame. The head is actuated in, any suitable well known manner.

6 is a compressible and expansible air chamber on the lower buck, this being of sufiicient size to contain, and, when compressed, displace a relatively large body of air.

The air chamber here illustrated comprises a metal bottom wall 7 and a circumferential wall 8 of metal in-the form of a bellows and a porous and foraminous top wall 9. Springs 10 are interposed between the top and bottom walls. The metal walls and springs all contribute to the quick heating of the air in the air chamber.

The top wall 10 of the air chamber is here shown as formed of a porous layer 10* and with foraminous plates as wire mesh 10 above and below the porous layer 10. The construction of this air chamber per se forms the subject matter ofanother application Sr. No. 115,064, filed June 10, 1926.

Although various forms of pads and spring ads have been used, the displacement 0 any air during the compression of the pad has been small and incidental only and not utilized or utilizable to any great extent, and the air chamber here illustrated is intended to displace a large body of air during the compression of the pad and in so doing force the air up through the top wall 10 of the chamber, drying the same and also through the garment or other article to remove the moisture therefrom.

The means for creating the draft of air .as here shown includes a fan 11 connected to the air chamber by a pipe 12 opening through the buck and the bottom of the air chamber, this pipe having a one wa rotary valve 14 therein. The fan 11 is pref erably a blower although it may be a suction fan.

Connections are provided between the yoke lever 3 and a valve 14, these connections being here shown as a gear 15 mounted on the yoke 3 coaxiallytherewith, and meshing with a rack 16 carried by a rod 17, which rod is pivoted at its lower end to one arm of a bell crank lever 18, the other arm of which is connected by a link 19 to a rock arm 20 on the valve 14.

Obviously when the head is up, the air from the blower 11 will be blown through the chamber 6 and heated and out through the top wall of the chamber 6 and the garment or other article; when the head is closed the valve 14 will be closed so that now air will be forced between the pressing elements andthrongh-the garment and the padding thereon by the compression and displacement of the air in the chamber 6.

What I claim is 1. In a pressing machine, a buck, a head movable toward and from the buck, a lever carrying the head, means for creating a current of air between the head and the buck,

valve means for controlling the flow of the current of air, a gear mounted concentric with the axis of the lever, a rack meshing with the gear and motion transmitting means between the rack and the valve means for actuating the air controlling means.

2. In a pressing machine a buck, a head movable toward and from the buck, a compressible and expansible air chamber on the buck, and having substantially air tight side and bottom walls and a porous top wall through which the air is' expelled from the chamber when the chamber is compressed by the head, and means for creating a draft of air through the chamber when the head is separated from the buck,

3. In a pressing machine a buck, a head movable toward and from the buck, a compressible and expansible air chamber on the buck, and having substantially air tight side and bottom walls and a porous top wall through which the air is expelled from the chamber when the chamber is compressed by the head, and means for creating a draft of air through the chamber when the head is separated from the buck, said means being controlled by the movement of the head.

In a pressing machine a buck, a head movable toward and from the buck, a compressible and expansible air chamber on the buck, and having substantially air tight side and bottom walls and a porous top wall through which the air is expelled from the chamber when the chamber is compressed by the head, and means for creating a draft of air through the chamber when the head isseparated from the buck, said means comprising a fan, a conduit connecting the fan casing and the interior of the air chamber, a controlling valve in the con duit and connections operated by the moveent of the head for opening and closing he valve. 1

In testimony whereof, I have hereunto signed my name, at Syracuse, in the county of Onondaga, and in the State of New York, this 29th day of May, 19:26.
